P0150 Code, A/F or O2 Sensor?

[jester125]

The engine light came on a few weeks ago so I got a code reader and it reads Code P0150. I've searched and found that the code means "Air Fuel Ratio Circuit Bank 2 Sensor 1" I cant seem to find that part, is it an O2 sensor or fuel/air sensor?

Thanks, Chris

Technically they are different, but for the sake of buying parts and replacing it they are the same..

I go to Rockauto.com and purchase NTK oxygen sensors, which is he OEM manufacturer of Nissan's air/fuel sensors and oxygen sensors. You can get the part number(s) at www.ngksparkplugs.com.

Thanks but I get this when I enter my info at NGK: "Sorry, we don't have any products in this category (Sensors) that fit your vehicle, but you can use the left-hand navigation to select a different product type."

Anyone have a part number? Are the 4 separate O2/AirFuel sensors the same?

thanks, Chris

Well, I'd be happy to help but you didn't give me the year or engine for your Pathy. For my 2006 Pathfinder with a 4.0L-V6, the NTK parts numbers are:

24320-front air/fuel sensor, right and left banks use the same P/N
24244-rear oxygen sensor, left
24247-rear oxygen sensor, right
